Growing interest is present in literature on the study of prospective memory functioning in Parkinson's disease (PD). Current data indicate that prospective memory may be impaired in PD and a relationship with general executive dysfunctioning has been suggested. However, although the dopamine dependency of cognitive dysfunction in PD has been widely investigated, poor is known on the dopaminergic modulation of PM. In the present study we explored the effect of acute administration of levodopa on the performance of a PD sample (n=20) in a time-based prospective memory task. PD patients were evaluated in the morning after a 12-hour therapy wash-out in two experimental conditions: i) after levodopa assumption ("on"); ii) without drug administration ("off"). The experimental task required to execute three uncorrelated actions after 10' for three consecutive trials. Distinct scores for the spontaneous recall of the intention to perform the actions (prospective component) and for the correct execution of the actions (retrospective component) have been computed. Results showed that in the "off" condition PD patients were selectively impaired on the prospective component of the task. However, L-dopa administration significantly improved PD patients' performance actually restoring the prospective memory deficit. These results support a critical role of dopaminergic modulation in prospective memory processes in PD patients, possibly through the replacement of dopamine levels in fronto-striatal pathways. 相似文献

Spatial updating allows people to keep track of the self-to-object relations during movement. Previous studies demonstrated that physical movement enhanced spatial updating in remote environments, but failed to find the same effect in described environments. However, these studies mainly considered rotation as a physical movement, without examining other types of movement, such as walking. We investigated how walking affects spatial updating within described environments. Using the judgement of relative directions task, we compared the effects of imagination of rotation, physical rotation, and walking on spatial updating. Spatial updating was evaluated in terms of accuracy and response times in different perspectives, and by calculating two indexes, namely the encoding and sensorimotor alignment effects. As regards response times, we found that in the imagination of rotation and physical rotation conditions the encoding alignment effect was higher than the sensorimotor alignment effect, while in the walking condition this gap disappeared. We interpreted these results in terms of an enhanced link between allocentric and sensorimotor representations, due to the information acquired through walking. 相似文献

Psychological and neurophysiological experiments require the accurate control of timing and synchrony for Input/Output signals.
For instance, a typical Event-Related Potential (ERP) study requires an extremely accurate synchronization of stimulus delivery
with recordings. This is typically done via computer software such as E-Prime, and fast communications are typically assured
by the Parallel Port (PP). However, the PP is an old and disappearing technology that, for example, is no longer available
on portable computers. Here we propose a convenient USB device enabling parallel I/O capabilities. We tested this device against
the PP on both a desktop and a laptop machine in different stress tests. Our data demonstrate the accuracy of our system,
which suggests that it may be a good substitute for the PP with E-Prime. 相似文献

The goal of this paper is methodological. It offers a comprehensive mapping of the theoretical positions on the ethical criticism
of art, correcting omissions and inadequacies in the conceptual framework adopted in the current debate. Three principles
are recommended as general guidelines: ethical amenability, basic value pluralism, and relativity to ethical dimension. Hence
a taxonomy distinguishing between different versions of autonomism, moralism, and immoralism is established, by reference
to criteria that are different from what emerging in the current literature. The mapping is then proved capable of (1) locating
the various theories that have been proposed so far and clarifying such theories’ real commitments, (2) having the correct
relationship with actual art making and art criticism practices, and (3) showing the real weight of the alleged counter-example
to a moralist position of a work that succeeds artistically because of its immorality.

Despite growing evidence that conversation on inner states fosters gains in children’s social cognition, this mechanism has yet to be tested with toddlers. To address this gap, we examined whether an intervention based on conversing about mental states with small groups of 2-year-old children at nursery had a significant effect on toddlers’ theory of mind (ToM) and emotion understanding (EU). Participants were 68 children (Mage at pre-test: 29.9 months) who were assigned to either an experimental or a control condition. Measures of verbal ability, ToM and EU were administered at pre-test, post-test and follow-up stages. Over a one-month intervention, all children were read a series of brief illustrated stories. After listening to the stories, the experimental group (n = 34) was involved in conversations on mental states, whereas the control group (n = 34) was engaged in conversation regarding the material entities and actions featured in the storybook. The experimental group significantly outperformed the control group on measures of both ToM and EU, independently of gains in verbal ability. Furthermore, these positive effects remained stable over time. We discuss the theoretical and practical implications of these findings. 相似文献

The representation of numerical and non-numerical ordered sequences was investigated in children from preschool to grade 3. The child's conception of how sequence items map onto a spatial scale was tested using the Number-to-Position task (Siegler & Opfer, 2003) and new variants of the task designed to probe the representation of the alphabet (i.e., letter sequence) and the calendar year (i.e., month sequence). The representation of non-numerical order showed the same developmental pattern previously observed for numerical representation, with a logarithmic mapping in the youngest children and a shift to linear mapping in older children. Although the individual ability to position non-numerical items was related to the child's knowledge of the sequence, a significant amount of unique variance was explained by her type of number-line representation. These results suggest that the child's conception of numerical order is generalized to non-numerical sequences and that the concept of linearity is acquired in the numerical domain first and progressively extended to all ordinal sequences. 相似文献

The present study investigated the role of self-construal in explaining psychological wellbeing in two European countries. Eight hundred and fifteen Italian and Scottish students completed measures of life-satisfaction, optimism, subjective happiness and a scale measuring interdependent and/or independent self-construal. We obtained three main findings. First of all, scores on the scales of psychological wellbeing were positively associated with scores on the independent scale and independence was found to be the factor that best explained variance in psychological wellbeing. Second, and contrary to our prediction, the Italian group had significantly higher scores for the independence scale than Scots. Third, gender was found to have a significant effect with regard to interdependence of self, life satisfaction, and optimism. 相似文献

During preadolescence children start to give attention to the future, to formulate thoughts, and to wonder about what they want. They also acquire knowledge and experiment with strategies to assist them in designing their future career. Among the constructs that can now play a relevant role in life designing, the four resources of career adaptability have a prominent role. This article reports the psychometric properties of the Italian version of the Career Adapt-Abilities Scale-International Form 2.0 for a group of middle school students. Two different studies involving Italian preadolescents were conducted. The first study tests the instrument's multidimensional structure, internal consistency and discriminant validity. The second one verifies the factorial structure's across-gender invariance and the test–retest reliability. Results provide strong psychometric support for the CAAS-Italian Form with preadolescents as a valid measure for analyzing their career adaptability and for using it in career counseling and education. 相似文献

For years, studies in the U.S. college population have described the phenomena of date and acquaintance rape. These phenomena have perpetuated myths regarding rape leading to the faulty labeling of the experience by the survivors themselves. Compared with the U.S., in Europe there are very few studies concerning this issue. This preliminary study in Italy comprised surveys of 210 participants who were asked to express their opinions on 2 scenarios of sexual assault (a forced rape and an acquaintance rape). Only 48% of the participants thought that acquaintance rape should be tried in a criminal court. 相似文献
